We also have a variety of spaces, including a children's play garden, rain gardens, a fully planted roof garden, a wildflower meadow, natural areas, green roofs, beds with mixed perennials and grasses, and numerous trees. Together, we deliver superior patient care, advance new discoveries and treatments through pediatric research, and serve as the pediatric and adolescent, academic medical center for Washington, Alaska, Montana and Idaho - the largest region of any children's hospital in the country.
